These are the prices for
the US listed
on the websites of proprietary software companies. Software companies
generally charge the same price for their software everywhere in the
world, so these prices can be taken as a rough guide for the rest of
the world as well, although you should contact the software companies
for the exact price in your country. Software companies also
generally charge the same license fee regardless of the version of
the software, so the prices for the latest version hold for older
versions as well. For instance, Microsoft charges businesses the same
license fee for computers with Windows 95 as computers with Windows
XP.

In practice, many of these
programs are
sold at less than list price by internet venders. Software can often
be bought at significantly cheaper prices, especially when sold with
new computers or with special academic or bulk discounts.
Nonetheless, the prices listed by the software companies' websites
are the prices that these companies expect us to pay so we should use
them in when trying to calculate the difference in cost between FLOSS
(Free/Libre/Open Source Software) and proprietary software. More
importantly, these are the prices that companies, schools,
ciber-cafes, governments and other organizations will have to pay if
they are busted for not having legal licenses for their software. The
Business Software Alliance (BSA) generally gives the offender a month
to buy licenses for all their illegal software at list price.

In the case of a university
like UNAMBA
in Abancay, Peru, every machine has roughly $2000 worth of software.
If UNAMBA were ever busted by the BSA, the school would go bankrupt
trying to pay for legal licenses for all its proprietary software.
